What's new in Altair Flux™ 2021.2
Altair EmployeeLet’s have a look at the key features and improvements of Altair Flux™ 2021.2 !
FREE SHAPE OPTIMIZATION
Taking benefit of the OptiStruct unique optimization techniques, Flux is now able to perform free shape electromagnetic optimization studies. You do not need to parameterize the geometry, just select the lines you want to consider to be changed in the optimization process. The optimizer will automatically adapt their shapes to maximize or minimize electromagnetic quantities, like the magnetic flux or the torque, while respecting volume (surface) constraints. This is available in 2D magnetostatic and transient applications in Beta mode. This will be a revolutionary tool to find innovative designs for any electromagnetic device!
CHARACTERIZATION OF AXIAL MACHINE PERFORMANCE IN AN EFFICIENT WAY
Axial machines are known to reach high power densities and they are of great interest for traction applications. A set of macros is now available in Flux to easily enter models of axial machines and perform classical calculations such as cogging torque, short-circuit analysis or efficiency maps.
EASIER DEFINITION OF 3D COILS
In the continuity of Flux 2021 and 2021.1, this new version brings even more flexibility to the definition of meshed coils, when being used with periodicities. Many limitations have been removed, enabling a smooth process to define coil conductor regions based on an imported CAD geometry.
Extended capabilities for E-Motor NVH analysis
For the NVH studies of electric motors, electromagnetic forces are computed in the air-gap of the machine on a support. Flux now offers more flexibility to define this support and expands the modeling capabilities, especially in 3D. This is very useful for studying the noise generated by axial machines. It can also be used to consider non-cylindrical air-gaps or for eccentricity studies.
LEARN HOW TO USE THE NEW SIMLAB INTERFACE FOR FLUX
As more and more Flux electromagnetic capabilities are introduced into Altair SimLab, new tutorials have been created for learning how to perform simple electric motor simulations inside this new interface. You can discover how to create a parametric 2D sketch of a surface permanent magnet motor using the SimLab sketcher. You can then define and run cogging torque, back-EMF and constant speed analysis. A second example is also available, dealing with the modeling of an interior permanent magnet machine. You can access these two tutorials directly using the following link: https://community.altair.com/csm?id=kb_article&sysparm_article=KB0116861
